feat: introduce fuel-telemetry macros

[kayagokalp]

Description

Add telemetry opt-out support to forc-tracing

This adds fuel-telemetry to forc-tracing (not quite - dependency is currently pointing to Github) with opt-out functionality for upstream tools like fuelup.

Usage

First, add it to the forc-tracing dependency:

[dependencies]
forc-tracing = { version = "0.47", features = ["telemetry"] }

Then use the telemetry::* glob, followed by the usual tracing macros, but with a _telemetry postfix:

use forc_tracing::{
    init_tracing_subscriber, println_green, println_red, println_yellow, telemetry::*,
};

fn main() {
    init_tracing_subscriber(Default::default());

    println_red("Stop");
    println_yellow("Slow down");
    println_green("Go");

    error_telemetry!("Error message for InfluxDB");
    warn_telemetry!("Warn message for InfluxDB");
    info_telemetry!("Info message for InfluxDB");
    debug_telemetry!("Debug message for InfluxDB");
    trace_telemetry!("Trace message for InfluxDB");
}

This will output the following (note DEBUG and TRACE messages are filtered out because of RUST_LOG=info):

> RUST_LOG=info ./target/debug/example
Stop
Slow down
Go

We can then peek into telemetry files like the following:

> cat ~/.fuelup/tmp/*.telemetry.* | while read line; do echo "$line" | base64 -d; echo; done

New: Telemetry Opt-Out Support

This PR also adds opt-out functionality for telemetry, allowing upstream tools like fuelup to disable telemetry collection:

Changes:

• Added --disable-telemetry CLI flag to main forc binary
• Added FORC_DISABLE_TELEMETRY environment variable support
• Updated all telemetry macros to respect the disable flag
• Added init_telemetry() function for proper initialization

Opt-out Usage:

# Disable via CLI flag
forc --disable-telemetry build

# Disable via environment variable  
FORC_DISABLE_TELEMETRY=1 forc build

# For upstream tools like fuelup
export FORC_DISABLE_TELEMETRY=1
fuelup toolchain install latest

Code example with opt-out:

use forc_tracing::{init_telemetry, init_tracing_subscriber, TracingSubscriberOptions};

fn main() {
    let options = TracingSubscriberOptions {
        disable_telemetry: Some(true),
        ..Default::default()
    };
    
    init_tracing_subscriber(options.clone());
    init_telemetry(&options);
    
    // Telemetry macros will now be no-ops when disabled
    error_telemetry!("This won't be sent to telemetry if disabled");
}

The implementation ensures telemetry is opt-out by default but can be easily disabled through either CLI flags or environment variables, making it suitable for upstream tool integration.

I believe * implies 0+ args; I believe we don't want scenario's where there are no args?

Suggested change

	($($arg:tt)*) => {{
	($($arg:tt)+) => {{

If so; may also apply to the macros below aswell

LGTM 👍
